I am using VB2005 ASP/VB. I have a Gridview placed on a web form which is popluated by a query based on user input.select * from view_main where initials = ddlfilter.textThis works fine. However I want to display a realtime record count based on that query and dump the info in a label called 'recordcount' which appears at the bottom of the grid.
I need to get the count of the records in my app. But BindingSource.Count always counts NewRow too if I select the new row. And this causes an exception. Is there any different method for it?
I have the code below which does work, but I need to add further functionality to it. The functionality I want to add to it is the text I have commented in the code below.
Dim objSQLConnection As SqlConnection Dim objSQLCommand As SqlCommand Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
[code]....
Before the if statement, I want to find out if the database already has records with the username in the strUser variable.
I am using a table adapter and the update code as below in a Try/Catch block as shown on the MSDN site.
Me.MyTableAdapter.Update(Me.MyDataSet.MyTable)
This all works fine but I should like to return to the user a MsgBox which displays the count of new records added and/or existing records amended.I know I could count the records in the underlying table before and after the update, the difference being the count of new records. How can I count amended existing records ?
I am new to this forum and I state that I am a beginner in visual basic. I need help with a program I'm doing for personal use. I have an Access database connected via wizard to visual basic 2010, from wizards automatically as I dataset and TableAdapter bindingsouce, a datagrid on the form and text, and buttons for various rescues etc.. My problem is that I need to do a count of duplicate data, I have a table Inserimento_veicoli (Ex. count model vehicles like the Fiat Punto) and I managed to find the right code
I have the following search code which works fine. However, I have an additional task to do, which is create a count function for the Record found or Record not found. Presently what it does is it searches and if a record is found it displays at the tooltip "Record Found" if not it says "Record Not found". However, sometimes you have 2 or more records. Therefore, the tooltip should say the exact amount of records found.. For example, 3 Records Found or even 5 Records Found. Also if only one record is found it says "Record Found" but if more it should display " 2 Records Found".

I need to count the number of records that match on the GIDs from the 'Directories' table (GID) and the 'ClientSubscriptions' table (DirectoryGID), and also the 'FranchiseGID' from both; as follows:

I'm trying to get a simple count of rows meeting some criteria. The value returned does not coincide with the correct number of rows when running the same query in Management Studio (SQL 2005)
vb.net Public Function RowsAffectedCount() As Integer Dim result As Integer = 0
[code]....
'result' always returns 1, but I have 3 records meeting that criteria in the database. Been staring at the code for a couple hours now and can't figure it out... I just need to know if the Count of rows returned from a SELECT statement is greater than 1 (at least two records).
I'm currently doing a project which requires me to count a specific number of records who have a certain checkbox marked as true, passed questionnaire, it then needs to display this result in a textbox when the form is loaded. However i am having problems displaying the result in the textbox, this is my current code.

I'd take both C# and VB.NET suggestion.I'm using LINQ to query data. I'm trying to query the parent and count the child tags.Here's my Tags table column:

I'm using VB.NET, and I'm trying to write a program for the company I work for, that interacts with a database designed for logging web site email submissions (After a user fills out a form for a item request or comment sheet, the email the form sends gets logged so we can more easily see which site gets spammed more, and we keep a record of the actual spam). My program mainly just makes the data easier to read. However, I want to add a feature so that a user can click a button, then an automatic query will take place so that all the preserved URLs in the database are tested, then a form will appear that states something along the lines of: These Sites Sent This Number of Emails
I am trying to debug my code, which involves a simple webservice that passes parameters to a data class, which calls a stored proc, and returns one row of record. I am not getting any error messages, but I am not getting any records back either.[code]
the total number of records for the previous day where the feed is, 1, 3 and 5 i.e.the feeds I need to retrieve totals for will just be selected based on what I need for instance it could be box4 and box 5...not specifically odd and even...I hope this makes it more clearer..what I have for all records:
select sum(count) as [total] from PostTable where Cast(dateinserted as DATE) = CAST(getdate()-1 as DATE)
I have the following SQL query to return all Customers who have no OrderLines with no Parts assigned - i.e. I only want the customers within which every order line of every order has no parts assigned - (in the actual problem I am dealing with a different domain but have translated to customers/orders to illustrate the problem)
SELECT c.Customer_PK FROM Customers c INNER JOIN Orders o[code].....
This works but generates less than optimal SQL - it is doing a subquery for Count on each row of the customers query rather than using Group By and Having. I tried making the LINQ Group By syntax work but it kept putting the filter as a WHERE not a HAVING clause.Edit in response to Answers below: I am accepting JamieSee's answer as it addresses the stated problem, even though it does not produce the GROUP BY HAVING query I originally had.I am a VB developer so I have had a crack translating your code to VB, this is the closest I got to but it does not quite produce the desired output:
Dim qry = From c In context.Customers Group Join o In context.Orders On c.Customer_PK Equals o.Customer_FK Into joinedOrders = Group[cod].....
The problem I had is that I have to push "jl" into the Group By "Key" so I can reference it from the Where clause, otherwise the compiler cannot see that variable or any of the other variables appearing before the Group By clause.With the filter as specified I get all customers where at least one order has lines with no parts rather than only customers with no parts in any order.

i supposed it can show the result of count(ID), in this instant it is the number of records count on the OUTBOX so the debug.writeline is RESULT, instead of now it is showing "SELECT COUNT(ID) FROM OUTBOX"
I'm getting an error on my index simply setting a string field prior to using it and entering the loop. When I set this field within the loop I get a error still. how to go about Inserting records based upon a query in vb .net? The following is the code that I have:
Public Sub Insert_RunsizeUPCs() Dim Command As SqlCommand Dim adapter As New SqlDataAdapter Dim dsin As New DataSet
Dim assSummary = From a In db.Assignments Join ur In db.UserRegions On a.Origin.ID Equals ur.Region.ID
[code]....
In the controller I can return the data easily as follows:
For Each c In assSummary MsgBox(c.Description & " " & c.AssCount) Next
If I pass the object through to the view using Viewdata("assSummary") = assSummary, how do I display the data? Every method I've tried results in messages about 'VB$AnonymousType_7(Of Integer,String) and I don't know how to retrieve the data from the anonymous type.
